Mitchel, who had been known as "The Boy Mayor of New York," died at the age of 38 in July 1918, less than seven months out of office, when he fell out of a single-seater scout plane he was piloting over Lake Charles, Louisiana.

In 2002 he graduated to the IndyCar championship, the top level of single-seater racing in the US, and the following year he joined the Andretti Green team, taking a seat following the retirement of Michael Andretti.

He had gone to bed miserable and resentful, planning yet another transfer, this time to a single-seater squadron, which he thought could never, under any circumstances, require liaison with the Royal Navy.

In December 1925, flying over Stonehenge at 2,000 feet in his single-seater Sopwith Snipe, he had spotted something in the corner of a field a couple of miles away: a large circle with oval rings of white spots in the centre.
